Serena Williams will enter the US Open with even more question marks after pulling out of the Western & Southern Open on Monday.Williams, the two-time defending champion in Cincinnati, cited a right shoulder injury, the same setback that forced her to withdraw from the Rogers Cup in Montreal last month.Im very disappointed Im not able to compete in the Western & Southern Open in Cincinnati, as I was really looking forward to defending my title, Williams said in a statement to the tournament. My shoulder inflammation continues to be a challenge, but I am anxious to return to the court as soon as possible.Williams did play in the Rio Olympics last week but fell to Ukraines Elina Svitolina in the third round. During that match -- one in which Williams double-faulted five times in one game late in the second set -- she was visibly bothered by her shoulder. She and sister Venus also lost in the first round of doubles.With her withdrawal, Williams is now in danger of losing her No. 1 ranking, which she has owned for 183 consecutive weeks, second all time to Steffi Grafs record of 186.If Rio silver medalist Angelique Kerber wins Cincinnati this week, she would unseat Williams atop the WTA Tours rankings. Earlier this season, Kerber won the Australian Open, her first major title, and at Wimbledon, she reached the final before running into Williams.Assuming she is healthy enough to play, Williams will next appear at the US Open, where she has a chance to pass Grafs Open era record of 23 Grand Slam titles.Williams will be replaced in the Western & Southern draw by lucky loser Misaki Doi of Japan.Custom Chicago Bears Jerseys . -- The Bishops Gaiters are showing they belong among the countrys top varsity football teams.

Third-string quarterback Bo Levi Mitchell led the Stampeders to an enormous rally on Saturday as Calgary stormed back from a 24-point deficit for a 38-27 victory over the Montreal Alouettes. "My mindset when I went in -- we just made the comeback -- was dont let the offence sputter," said the 23-year-old Mitchell, a second-year pro from Eastern Washington University. "We had to make sure we went out there and got a couple of touchdowns and get ahead in this game." The Alouettes suffered their third straight loss under new head coach Dan Hawkins and are 1-3. The Stampeders improved to 3-1. Jon Cornish scored a pair of second-half touchdowns and Mitchell led two drives after coming on for starter Kevin Glenn, who injured his right elbow in the third quarter. Mitchell finished with a pair of TD passes on 7-of-13 throwing for 49 yards. He also had a 26-yard run. Glenn was starting for the second straight week in place of Drew Tate, who strained a muscle in his right arm in a loss to the Saskatchewan Roughriders July 5. Mitchell came on when Glenn was rocked by Aaron Lavaris when delivering a 45-yard pass to Marquay McDaniel. Glenn didnt appear too hurt after the contest. "I never got the strength back in it," he said. "I felt the way the game was going it was best if Bo went in and gave us a spark." It looked like Montreal was going to take out its offensive frustration on the Stampeders after back-to-back losses at home, including a 22-14 loss to Calgary last week. The normally explosive Anthony Calvillo-led Montreal offence scored only 11 points in a defeat at the hands of the Winnipeg Blue Bombers the week before that. The Alouettes put up three touchdowns and a field goal to open up a 24-0 lead after one quarter. Drives of 82 and 79 yards were capped off by Brandon Whitakers two-yard scoring run and S.J. Greens catch-and-run for a 59-yard score. Jerome Messam ran in from four yards. That was most of the Alouettes offence, though. Calvillo was 9-of-13 for 167 in the first half but 9-of-17 for 76 in the second. "Its frustrating when youre losing, especially when everyone is playing so hard," said Calvillo, who turns 41 in August. "We did solid out therre in the first quarter but after that .dddddddddddd . . . Im not saying we went back to our old ways, but we were inconsistent. I cant tell you why, but today thats the way it was for whatever reason." Calgary woke up and dominated after the first quarter, during which they only had 23 total yards. Mitchell, who saw spot duty in the game before Glenns injury, lobbed a one-yard TD pass to Tim St. Pierre. Glenn found Nik Lewis with a five-yard strike and Rene Parades kicked field goals of 27 and 41 yards to close the gap to 24-19 at the break. The Stampeders took the lead for good with 4:57 left in the third quarter. Mitchell found Cornish with an 11-yard scoring pass to finish off a 89-yard drive for a 28-24 advantage. The Alouettes looked like they would get the lead back on the ensuing kickoff. Noel Devine was about to cross the Calgary goal-line on the return but Fred Bennett punched the ball loose and it was recovered in the end zone by Alvin Bowen. "It was the play of the game," said Stampeders head coach John Hufnagel. "That was a 14-point swing. It took seven points off their board and we got the ball at the 25 and marched down for a touchdown. "It was kind of an indication of our team in this game. No matter how bad it looked we played to the last whistle and never gave up." The Stampeders indeed drove again right away and Cornish ran in his second touchdown from 21 yards out. Cornish finished with 109 yards on 11 rushing attempts. Paredes finished with four field goals to close to within one of tying B.C. Lions Paul McCallum for the CFL record of 30 consecutive regular season field goals. His tying attempt from 35 yards with 1:04 to go was blocked by John Bowman. It doesnt count as a missed field goal, but is considered a fumble. NOTES - Scratches for Calgary were linebackers Jonathan Hefney and Yannick Carter, receiver Maurice Price and offensive lineman Spencer Wilson . . . Out for Montreal were receiver Tyson Carrier, offensive lineman Anthony Barrette, defensive tackle Moton Hopkins and defensive end Bo Adebayo. . .
