FOXBOROUGH, Mass. (AP) — Tom Brady is back at practice one day after hurting his knee.

The New England Patriots quarterback is taking part in the third day of joint practices with the Tampa Bay Buccaneers. It isn’t known if he’ll play Friday night when the teams meet in an exhibition game.

Brady jogged from sideline to sideline with his teammates at the start of practice.

He sprained his left knee about midway through Wednesday’s practice when Tampa Bay defensive end Adrian Clayborn knocked New England left tackle Nate Solder into him. Brady fell down and left the field briefly. He returned for several more plays before walking off under his own power.

In his absence, Ryan Mallett played with the first offensive unit and Tim Tebow quarterbacked the second team.

Patriot moves

The Patriots have cut veteran wide receiver Michael Jenkins.

They’ve also released offensive lineman Kevin Haslam and placed offensive lineman Tyronne Green on injured reserve. Both were longshots to make the team.

The Patriots signed Jenkins on March 28 as a free agent from the Minnesota Vikings where he spent the past two seasons. He played the first seven seasons of his nineyear career with the Atlanta Falcons.

In 130 NFL games, Jenkins had 354 catches for 4,427 yards and 25 touchdowns. Last season, he had 40 receptions for 447 yards and two touchdowns. The Falcons drafted him with the 29th pick in the first round in 2004.

Haslam spent last season with San Diego after two with Jacksonville. Green played the last four seasons with San Diego.
