INDIANAPOLIS (AP) -Marvin Harrison has played through the tingling in his left hand for nearly a month.

Rookie running back Joseph Addai might need to follow the 11-year veteran's lead when it comes to his injured right ankle.

The Indianapolis Colts (11-3) need both playmakers to make a playoff charge.

Harrison, in line for his eighth straight Pro Bowl selection Tuesday, hasn't let team doctors examine the hand nor has he missed any practice time, although coach Tony Dungy acknowledged it has bothered the receiver.

``I think it will be that way the rest of the year,'' Dungy said of Harrison, who had surgery on his elbow in May. ``But he doesn't seek treatment and he doesn't seek a diagnosis. I think there's only one person who knows what it is, but I do know that if the ball hits it a certain way, it tingles.''

Addai rolled his right ankle Monday night on a 41-yard run - the Colts' longest of the season - to set up Manning's third touchdown pass to Harrison.

Dungy said after the game and Tuesday that it was not a high-ankle sprain and he expected Addai to play Sunday in his hometown of Houston.

``I heard on the news reports that it was a high ankle sprain, and I thought I made it pretty clear last night that it wasn't,'' Dungy said. ``It's a basketball-type sprain. It's sore, but I think he should be OK.''

Addai leads all rookies with 917 yards rushing and is trying to become the fourth Colts first-year player since 1994 to top 1,000 yards. The others were Marshall Faulk in '94, Edgerrin James in '99 and Dominic Rhodes in 2001, when he set the NFL record for undrafted rookies with 1,104 yards.

Harrison's production has remained high despite his hand problem. The steady receiver has caught 82 passes for 1,180 yards and nine touchdowns. He's topped 80 catches and 1,000 yards eight straight years and needs one more score to become the only active player with 10 TD receptions in eight straight seasons.

In Monday night's 34-16 win over Cincinnati, Harrison had eight catches for 86 yards and a season-high three touchdowns.

The biggest question on offense remains tight end Dallas Clark, who has missed three straight games since injuring his right knee against Philadelphia.

Initially, the Colts feared Clark tore the anterior cruciate ligament, which Dungy said isn't the case.

``It is an ACL injury, but it's not a tear. It's healing on its own,'' Dungy said. ``They told us it was an ACL and that he was out and then they came back the next day and said `We thought it was torn, but it's not.'''

Dungy said Clark could return for the regular-season finale against Miami, but more likely would return for the playoffs.

``That's why it's important to keep winning and get the bye, so some of these guys can rest and heal,'' Dungy said.

He didn't update the conditions of the Colts three safeties who missed Monday night's game with injuries - Bob Sanders (knee), Antoine Bethea (shoulder) and Marlin Jackson (shoulder).

Sanders has played only two games since having arthroscopic surgery after a Week 2 victory over Houston. Bethea and Jackson were both injured in the Colts' 44-17 loss at Jacksonville a week ago.
