The Kansas City Chiefs appear to have dodged a bullet on quarterback Patrick Mahomes' right knee injury, which he suffered in Thursday night's 30-6 win over the Denver Broncos.

Head athletic trainer Rick Burkholder on Monday provided an update on Mahomes' MRI procedure, which was administered Friday, and sounded highly encouraged with the results.

"That turned out as good as we could possibly imagine," Burkholder said.

Mahomes immediately began the rehabilitation process, which included "extensive pool therapy" over the weekend at the Chiefs' training facility and is "progressing nicely," Burkholder said.

Numerous reports over the weekend suggested Mahomes, who suffered a dislocated kneecap in the second quarter against the Broncos, could be back in three to six weeks.

Burkholder, though, stopped short of providing a specific timeline on Mahomes.

"Every guy is different and every injury is different," Burkholder said. "We'll manage Patrick accordingly and he's right in the middle of the process."

Ryan streak may end

Falcons quarterback Matt Ryan's decadelong streak of consecutive starts is on the line because of a sprained right ankle.

Coach Dan Quinn said Ryan ran in a pool Monday to test the ankle and has not been ruled out for Sunday's game against Seattle.

The 34-year-old Ryan has not missed a start since 2009. His streak covers 154 regular-season games.

Dolphin faces discipline

Dolphins safety Bobby McCain will be disciplined by the team for a verbal confrontation with a 13-year-old boy and for allegedly spitting in the face of another Bills fan following Miami's loss at Buffalo.

The fan, 28-year-old Dylan Wentland, said he was standing at the ledge overlooking the tunnel when McCain ran up and spit in his face following the game. Wentland said he and McCain exchanged words before the game when McCain twice threatened to spit at a teen.
