The Indianapolis Colts added wide receiver Michael Pittman to their Week 5 injury report Thursday with a hamstring issue.

Pittman was a limited participant in practice on Thursday ahead of Sunday’s home game against the Las Vegas Raiders.

The sixth-year pro caught five passes for 41 yards and a touchdown while playing his usual heavy allotment of snaps last weekend as the Colts (3-1) fell on the road to the Los Angeles Rams.

Pittman is the top target for resurgent quarterback Daniel Jones. He has a team-high 21 receptions for 234 yards (11.1 per catch) and three scores.

The Colts enter Week 5 with a plus-40 point differential that ranks fourth in the NFL. They’re also fourth in points scored (30.8 per game) and net passing yards (261 per game).

Indianapolis co-leads the AFC South with the Jacksonville Jaguars, who host the Kansas City Chiefs on Monday night.

Defensive end Tyquan Lewis (oblique) also landed on Thursday’s injury report. Veteran cornerback Xavien Howard abruptly retired for family reasons earlier in the week after starting each of the Colts’ first four games.
