Rashee Rice injury update: Adam Schefter details uncertainty surrounding Chiefs WR's knee

The Kansas City Chiefs (4-0) remain uncertain on the extent of star receiver Rashee Rice 's right knee injury, according to Adam Schefter of ESPN .

After undergoing an MRI Monday, additional tests are required to determine the full extent of the injury, as well as a recovery timeline. No answers are expected until next week, Schefter noted. Rice was initially feared to have suffered a torn ACL in Sunday's 17-10 Week 4 road win over the Los Angeles Chargers (2-2).

Rice sustained the knee injury in the first quarter after quarterback Patrick Mahomes accidentally hit him low while attempting to make a tackle on cornerback Kristian Fulton , who had picked him off earlier in the play.

Chiefs thin at WR after Rashee Rice injury

Head coach Andy Reid offered a grim update on the reality of Rice's injury while speaking with the media after the game.

"Rashee will have his knee checked out tomorrow with an MRI," Reid said. "It's his knee, and I think we'll have to wait and see, but I'm sure it's not as good of news as we want."

Rice, the 2023 second round pick out of , entered Sunday's game third in the with 24 receptions to go along with 288 yards and two touchdowns. His absence will be felt, as Kansas City's receiver room is already thin following the loss of Hollywood Brown .

Several Chiefs stepped up with Rice sidelined, none more so than tight end Travis Kelce . Kelce, held to just eight receptions for 69 yards in the first three games of the season, came down with a team-leading seven catches for 89 yards in the victory over Los Angeles. Rookie wideout Xavier Worthy added 73 yards on three receptions, including a 54-yard score late in the second quarter.

Reid said he felt the team "hung together" the "best way they could" after Rice went down.
