Funchess caught 3-of-5 targets for 32 yards on Sunday.
Funchess was brought in to complement T.Y. Hilton as the Colts’ No. 2 receiver this year, but his injury could push Deon Cain, Chester Rogers and rookie Parris Campbell into larger roles moving forward.
Funchess, 25, is a former second-round pick by the Panthers in the 2015 NFL Draft out of Michigan. He finished his four-year rookie contract with Carolina before agreeing to a one-year deal worth up to $13 million with the Colts this offseason.
Funchess will once again be an unrestricted free agent in 2020.
In 2018, Funchess appeared in 14 games for the Panthers and recorded 44 receptions for 549 yards receiving (12.5 YPC) and four touchdowns. Pro Football Focus rated him as the No. 54 overall receiver out of 117 qualifying players.
