Matthew Stafford connected with rookie Puka Nacua on a 22-yard touchdown pass on the first possession of overtime as the visiting Los Angeles Rams earned a 29-23 victory Sunday against the Indianapolis Colts after blowing a 23-point lead.

The Rams went 75 yards on their overtime drive with Nacua scoring his first career TD on a third-down play. The BYU product made NFL history twice, with his 39 receptions and 501 receiving yards both marking the most in a player's first four career games.

Kyren Williams scored two first-quarter touchdowns for the Rams (2-2) and had 103 yards on 25 carries. Stafford was 27-of-40 passing for 319 yards and one interception with his touchdown as he was hobbled in the second half by a right leg injury. Nacua had nine receptions for 163 yards.

The Colts rallied to tie the game 23-23 with 1:56 remaining on a 5-yard TD pass from rookie quarterback Anthony Richardson to Drew Ogletree, then getting a two-point conversion on a Michael Pittman Jr. reception. It was Ogletree's first career touchdown.

Richardson was 11-of-25 passing for 200 yards and two TDs in the air, while getting another on a fourth-quarter run after missing last week's victory over the Baltimore Ravens with a concussion.

Zack Moss had 18 rushes for 70 yards and Richardson ran the ball 10 times for 56 yards for the Colts (2-2), who have lost both of their home games this season.

The Rams turned the opening possession of the game into a 7-0 lead on a nine-play 75-yard drive that ended with Williams' first TD. Los Angeles topped that in its second drive, going 94 yards in 10 plays, with Williams scoring another short TD run.

The Rams scored points on each of their first four drives of the game, getting 40-yard and 54-yard field goals from Brett Maher in the second quarter to take a 20-0 lead.

Los Angeles took a 23-0 lead on a 51-yard field goal from Maher with 7:17 remaining in the third quarter before the Colts began their comeback.

Richardson threw a 35-yard TD pass to Mo Alie-Cox with 5:26 remaining in the third quarter for the Colts' first points of the game. A reception by Moss earned them the two-point conversion and a 23-8 deficit.

Richardson scored on a 1-yard TD run with 11:45 remaining to pull Indianapolis within one possession at 23-15.
