FOXBORO, Mass. — There was some mystery about who would play quarterback for the Kansas City Chiefs in their game against the New England Patriots.

There was none about who would try to knock down that quarterback's passes as New England's free safety on Monday night.

It's Tebucky Jones, who finally has found his role after spending two mediocre NFL seasons moving between cornerback and safety as he started just two games.

"He's done a pretty solid job," Patriots coach Bill Belichick said. "He's made steady improvement."

New England already has two Pro Bowl players in the secondary, cornerback Ty Law and strong safety Lawyer Milloy.

"I knew it was going to take him (Jones) time" to develop, Chiefs coach Gunther Cunningham said. The Patriots "move around well on defense, but I think we've played those kind of teams before. We've just got to play our own game."

Passing is the strength of the Chiefs' offense, especially when Elvis Grbac plays quarterback.

He is 3-1 in Monday night games but was listed as questionable. He was optimistic he would play after a finger injury kept him out of a 17-16 loss to San Diego in Kansas City's last game as Warren Moon struggled in his place.

The Chiefs (5-7) have lost their last four games but have a strong receiving corps with Tony Gonzalez, Derrick Alexander and Sylvester Morris. With Grbac throwing, the challenge would be much greater for the Patriots secondary.
