Jets’ Darnold out indefinitely with mono

FLORHAM PARK, N.J. — Sam Darnold is sick and sidelined — likely for several weeks.

New York Jets coach Adam Gase announced Thursday the second-year quarterback has mononucleosis and will miss at least the team’s game against the Cleveland Browns on Monday night.

Trevor Siemian will start in Darnold’s place, and could be the starter moving forward until Darnold recovers. The Jets have a game at New England in Week 3 before they have a bye-week break, and then games at Philadelphia, at home against Dallas and New England before a road game at Jacksonville on Oct. 27 to cap a rough opening stretch.

Brewers’ Yelich likely done for year

MIAMI — Milwaukee Brewers star Christian Yelich won’t need surgery on his broken right kneecap, but the team says it’s unlikely he’ll return this season.

Brewers general manager David Stearns says Yelich’s recovery is expected to take eight to 10 weeks. Yelich was back in Milwaukee for tests on Wednesday, a day after the reigning NL MVP fouled a ball off his leg during a game in Miami.

Yelich hit .329 with 44 home runs and 97 RBIs along with 30 stolen bases. He was leading the majors in slugging percentage and OPS when he was hurt.

Knee surgery ends Ohtani’s season

ANAHEIM, Calif. — Shohei Ohtani will miss the rest of the Los Angeles Angels’ season to have surgery on his left kneecap.

The Angels announced the decision Thursday. Los Angeles (67-80) has been eliminated from playoff contention with 15 games left.

Ohtani will need eight to 12 weeks to recover from surgery on a bipartite patella, or a two-part kneecap, according to the Angels. The team didn’t specify the reason for addressing the condition now.

Ohtani finishes his second major league season batting .286 with 18 homers and 62 RBIs in 106 games as the Angels’ designated hitter.

Bills rookie linebacker Dodson suspended

ORCHARD PARK, N.Y. — The NFL has suspended Buffalo Bills rookie linebacker Tyrel Dodson for six games as a result of an alleged altercation with his girlfriend at a nightclub in Scottsdale, Arizona.

An NFL investigation ruled Dodson violated the league’s personal conduct policy, the Bills announced Thursday. Dodson spent the offseason practicing with the team before being placed on the reserve/commissioner’s exempt list on Aug. 31, when the Bills made their final cuts to establish their regular-season roster.

Dodson was an undrafted rookie free agent out of Texas A&M, and signed with Buffalo on May 9.

Redskins’ Guice has knee surgery

ASHBURN, Va. — Washington Redskins running back Derrius Guice had right knee surgery that coach Jay Gruden called a “minor procedure.”

Renowned surgeon Dr. James Andrews performed the operation Thursday that has been reported to fix a torn meniscus. Guice was injured Sunday in a season-opening loss at Philadelphia when he rushed for just 18 yards on 10 carries and underwent an MRI the morning after.

Gruden says he isn’t sure how long Guice might be out and no decision has been made on whether to place him on injured reserve.

Guice missed all last season after tearing the ACL in his left knee in an exhibition game in August 2018. Gruden praised Guice for coming back strong from the torn ACL and expects the same this time because it’s not as major of a surgery.
