Funchess has three touchdowns on 41 catches for a team-leading 516 receiving yards, but he has been limited to five receptions for 71 yards in back-to-back losses at Pittsburgh and Detroit.
A second-round pick of the Panthers in the 2015 NFL Draft, Funchess established career highs with 63 catches for 840 yards and eight touchdowns last season.
The 6-foot-4, 225-pound Funchess has missed only one game in his three-plus seasons. But while his situation looks bleak, fellow wideout Torrey Smith returned to practice Thursday after sitting out four weeks due to a knee injury.
Rookie D.J. Moore, Carolina's first-round pick (No. 24 overall) in this year's draft, is coming off a monster game against the Lions with seven receptions for 157 yards and a touchdown.
