Chargers open practice window for DE Joey Bosa

Los Angeles Chargers defensive end Joey Bosa was designated to return to practice Thursday, bringing him closer to a return from injured reserve.

Bosa, 28, last played Nov. 19 at Green Bay when he was carted off the field during the game's opening series with a foot injury.

Thursday's move opens Bosa's 21-day practice window, although he was ruled out for a return this Sunday against the Buffalo Bills. Los Angeles still games remaining against the Denver Broncos and Kansas City Chiefs after Sunday.

Bosa has 20 tackles, 6.5 sacks and one forced fumble in nine games (five starts) this season.

A four-time Pro Bowl selection, Bosa has totaled 321 tackles, 67.0 sacks, 15 forced fumbles and four fumble recoveries in 93 games (84 starts). He was selected by the Chargers with the third overall pick of the 2016 NFL Draft out of Ohio State.

The Chargers also have ruled wide receiver Keenan Allen (heel) out of Sunday's game, while cornerback Essang Bassey (concussion), and defensive lineman Nick Williams (shoulder) are questionable. Defensive back Deane Leonard (heel) and linebacker Tanner Muse (knee) are doubtful.
