After suffering a season-ending knee injury on Sunday against the Los Angeles Chargers, Kansas City Chiefs quarterback Patrick Mahomes will go to Dallas for a second opinion.

DALLAS (KCTV) - Patrick Mahomes’ rehab process is underway, just one day after the three-time Super Bowl winning quarterback tore the ACL in his left knee. The Kansas City Chiefs announced that Mahomes underwent surgery Monday night in Dallas.

The two-time MVP will miss the rest of the season with an ACL injury. Here's the latest on his status and timeline to return.

Sunday was a brutal day for the Kansas City Chiefs, who lost their starting quarterback and had their playoff hopes crushed.

The Chiefs' head athletic trainer said nine months is the standard recovery time for an injury like Mahomes', give or take a month or two.

Chiefs vice president Rick Burkholder outlined Patrick Mahomes' recovery timeline after the quarterback suffered ACL and LCL injuries in Sunday's loss to the Chargers.

In Week 16 against the Tennessee Titans, the Kansas City Chiefs suffered a 26-9 loss. Patrick Mahomes was absent, and Chris Oladokun stepped in as the only healthy quarterback. The defeat added to a season already reeling from key injuries.
