Answer based on context:

This Week 12 showdown between the Colts and Eagles was originally scheduled for 1:00 ET, but due to the NFL's "flexible-scheduling" system this year, the NFL moved the game to Sunday night at 8:15 ET. This was the Colts' third primetime game this year on NBC, and the Eagles' first. There were 10 scores in this game, 5 each half. The first three scores of the game were by Colts rookie RB Joseph Addai. He had a 15-yard TD run, a 10-yard TD run, and another 15-yard TD run after that. His fourth rushing touchdown of the game came in the second half. The Eagles' first score came with about a minute to go in the half. Quarterback Jeff Garcia threw a 1-yard touchdown pass to L.J. Smith on that drive. On the Colts' next drive, combined with a couple passes and a 13-yard run by Dominic Rhodes, the Colts put K Adam Vinatieri in field goal range to get some more points before the end of the half. At the half, the Colts had a 17-point lead, 24-7. After a Reggie Wayne touchdown catch, the Colts were up big on the Eagles, 31-7. On the ensuing possession for the Eagles, Garcia found Reggie Brown in the end zone for a  3-yard score. But with less than 11 minutes left in the game, the Eagles scored once more and reduced the Colts' lead to 10 points. On the following possession, the Colts ran the ball 13 times with no passes and Joseph Addai had the last 8 carries on that drive including another 4-yard scamper, his fourth touchdown of the game. That touchdown also tied the Colts franchise record for the most rushing touchdowns in a single game. With less than four minutes to go in the game, the Eagles were desperate to score some points, but while Jeff Garcia was deep in his own territory, he dropped back to pass and was hit by both DE Robert Mathis and DE Dwight Freeney. Mathis knocked the ball out of Garcia's hand right before his arm started going forwards and CB Kelvin Hayden picked up the ball and ran it back for a touchdown. The Colts were up by 24 points after that last score. On the next possession, the Eagles put in backup QB A. J. Feeley in place of Garcia, and Feeley ended up getting the football knocked out of his hand by Robert Mathis (his second forced fumble of the game) and the Colts recovered and ended up running out the clock to conclude the game. Joseph Addai tied the NFL record for most touchdowns in a game by a rookie, with 4 touchdowns in this game. During this game, the Colts lost SS Antoine Bethea, TE Dallas Clark and OT Ryan Diem all to injuries in the first half, and they did not return.
