On Friday, the Bucs' veteran left guard missed practice for a second consecutive day because of a groin injury. Mankins, who's officially listed as questionable, suffered the injury in practice Wednesday.
"I don't know yet," Mankins said Friday. "It's day-by-day right now. I would love to [play], but we've just got to wait and see.
"If I can go, I'll go. If I can't, I can't."
Mankins, 33, has played 40 consecutive games, with 20 of them coming with the Bucs since Tampa Bay traded for him before the 2014 season.
Bucs coach Lovie Smith said Mankins is healing. The lineman was seen walking on the practice fields Friday while wearing a white cap, red shorts and his white No. 70 practice jersey.
"Getting better," Smith said. "But we held him out another day. We'll see how that plays out this week."
In other injury news, cornerback Johnthan Banks (knee), tight end Austin Seferian-Jenkins (shoulder), wide receiver Russell Shepard (hamstring) and center Evan Smith (ankle) are doubtful. Defensive tackle Gerald McCoy (shoulder) and tight end Luke Stocker (hip) are questionable. Safety Major Wright (abdomen) is probable.
