The Chiefs remain one of three NFL teams with a perfect record, but the schedule is turning rugged starting with this Sunday’s game at the Seattle Seahawks.

After four weeks of the NFL season, the Chiefs are one of three teams to stand 4-0, but remaining undefeated wasn’t easy ... and it was costly from an injury standpoint.

The Chiefs outlasted the Las Vegas Raiders 30-27, but lost wide receivers Tyquan Thornton and Rashee Rice during the game. Thornton’s ankle injury is more serious than Rice’s hamstring strain and Thornton is likely to miss the rest of the regular season.

How does this affect the Chiefs, and do they sign a free agent, like former Chiefs star Tyreek Hill? Beat writer Pete Sweeney is here to discuss all the options on SportsBeat KC, the sports podcast of The Star and KCUR (89.3 FM).
