Harrison optimistic, but remains cautious

INDIANAPOLIS -- Colts wide receiver Marvin Harrison might
return for Sunday's game at Buffalo after sitting out last weekend
with a strained right hamstring.

Harrison on Friday took part in his first full practice since he
injured his leg during the Nov. 9 game at Jacksonville. A final
decision on whether he will play won't be made until Saturday.

"I feel good," Harrison said after Friday's workout. "But
we'll have to see what happens. I just don't want to do anything
stupid to reinjure it. But right now, it feels real good."

Harrison is the top receiver for the Colts (8-2) with 56
receptions for 777 yards and seven touchdowns.

Colts coach Tony Dungy said he was optimistic about Harrison
playing this week.

"The question is do you take the risk, and how much and how
many plays and do you start him?" Dungy said. "He's basically
only practiced once."
