TONIGHT’S GAME

PITTSBURGH (4-2) AT KANSAS CITY (4-2)

* Kickoff: 5:15 p.m.

* TV: Channel 7

* Story line: When last seen on Monday night football, Elvis Grbac was holding his shoulder and grimacing. A vicious double-hit by Pittsburgh’s Nolan Harrison and Jason Gildon broke Grbac’s collarbone and sidelined him for six weeks. Now, almost a year later, those same Steelers are back in the same stadium tonight. “I’m not going to think about it. I’m just going to go out there and play the best I can and get out of here with a win,” Grbac said. It has been almost 12 months since Grbac started and finished a game that Kansas City won. In this season’s opener against Oakland, he separated his shoulder and was sidelined four games until the Chiefs’ last game, a 40-10 loss to New England. While Grbac has been on the mend, Pittsburgh quarterback Kordell Stewart has been on the run. Adjusting to a new offensive scheme and working behind a patched-up offensive line, Stewart has even been booed in Three Rivers Stadium. The Steelers rank 30th with 192 passing yards a game and Stewart has been sacked 16 times. He was sacked only 20 times all last year. The Chiefs are first in pass defense with 146.7 yards allowed a game. Chester McGlockton, a 320-pound defensive end who came from Oakland to Kansas City in the spring, will play his first regular-season game for the Chiefs. McGlockton played in only the first exhibition game in Japan before developing a back problem that led to surgery in September.

* The Line: Chiefs by 3.
