Bucs FS Tanard Jackson has been added to the 53-man roster, and according to the Pewter Report, the team has been impressed by his practice play enough to activate him for Sunday's game against the Saints.

Jackson, who was reinstated on Tuesday after a 19-game suspension by the NFL for failing drug tests, reportedly looked good in the Bucs' practice on Wednesday, earning the praise of Tampa Bay DBs coach Jimmy Lake.

"He looked great," Lake said of Jackson. "He looked like he has been working out. He is in great shape and looks like he actually has a little more muscle on him than he had last time I saw him. He looks ready to go.

"There is definitely a chance (he could play Sunday). We had a really good meeting last night. He was spitting out some of the coaching points. He was finishing my sentences, which is a good sign. Then this morning we had another good meeting. We will see how the week goes as he progresses and how he looks on tape in practice and then we will make that decision before game time."

The Buccaneers had two weeks to decide whether or not they wanted to activate Jackson from the exempt/commissioner's permission list, but they needed only three days to make their decision. The team had cleared a roster spot for Jackson on Thursday, waiving rookie RB Allen Bradford.

A fourth-round pick in 2007, Jackson has started all 46 games he has played. He has 29 career passes defensed and eight interceptions, with five forced fumbles, two defensive touchdowns and one sack.

Jackson was first suspended in 2009 for four games for violating the league's substance-abuse policy. He was then suspended again on Sept. 22 of last year.
