Portis, in December 2008. (RICKY CARIOTI / THE WASHINGTON POST)

Portis was in Boston on Friday for a workout with the New England Patriots and, according to multiple reports, he was svelte but hardly in football shape. Portis, who’ll turn 30 on Sept. 1, was released by the Washington Redskins in late February.

Although Portis is the second-leading rusher in Redskins history, his final two seasons were plagued by injuries (most recently, an abdominal tear and concussion). He hasn’t gained 1,000 yards since 2008 and last year gained just 227 on 54 carries.

“He’s lost his burst, which is understandable and comes with time and it would be doubtful that a lot of teams would have interest in him,” Charlie Casserly told Mike Jones of The Post in February. “And at this point wherever he goes he’d be playing for the league minimum and I don’t know why he would want to do that.”

As his production declined, he still retained value in pass protection, something that might make him attractive to the Patriots, who seem to be taking a look at every free agent this side of Tiki Barber and Terrell Owens.
