Kansas City, Mo. ? Cornerback Patrick Surtain was one of five Kansas City Chiefs undergoing MRIs on Monday, but he probably is the only player whose availability for Sunday might be in question.

Surtain, who has been the Chiefs’ only consistent cornerback, hurt his knee during their 28-20 loss Sunday at San Diego.

“We’re waiting on the MRI on Patrick Surtain. I’ll know more tomorrow,” coach Dick Vermeil said Monday. “He didn’t have any lateral movement on it.”

Backup cornerback Dexter McCleon, who has been sidelined, could be ready for Sunday’s game with Oakland.

“I’d say there’s a good chance he will be,” Vermeil said.

Also undergoing MRIs in the wake of a loss that left the Chiefs 4-3, two games behind Denver in the AFC West, were guard Will Shields, defensive end Gary Stills, cornerback Eric Warfield and safety Jerome Woods. Vermeil said that was not an unusual number.

“It’s pretty much a normal Monday around here,” he said.

Quarterback Trent Green will miss Wednesday’s practice to attend services in St. Louis for his father, Jim Green, who unexpectedly died Thursday. Team president and general manager Carl Peterson and some other representatives of the organization also will attend.

Green, despite the shock of losing his 58-year-old father, recovered from a shaky first half against the Chargers and had his best game of the year. Despite spotty pass protection, he hit 31 of 43 passes for 347 yards and two touchdowns.

“He hit 72 percent of his passes and had two dropped, and threw a couple for touchdowns,” Vermeil said. “He had a quarterback efficiency rating of 111. It’s just amazing. That’s the kind of person he is. He didn’t want (his father’s death) to be the center and focus on Sunday.”

Although the Chiefs would never say so, they’re probably looking at the softest part of their schedule. They’re home this week against the Raiders (3-4), whom they already beat in Oakland, then have road trips to Buffalo (3-5) and Houston (1-6).

If they’re to stay in the AFC West, they had better win all three.

They also have home games looming with Denver and San Diego after going 1-2 in their three road trips to their AFC West rivals. They beat Oakland and lost to Denver and the Chargers.

“I feel we should have won more than one,” Vermeil said. “At San Diego, we had an opportunity, and a good team beat us. We lost to a good team in Denver. Now, we’ve got an opportunity to get it done at home.”

Beating the Raiders, who have won two in a row, would seem paramount.

“They’re all important,” Vermeil said. “When you get to the eighth game of the season and you’re 4-3 and playing division games at home, they are magnified.”
