Phoenix Cardinals quarterback Timm Rosenbach said yesterday that he will undergo knee surgery and miss the 1991 NFL season.
Rosenbach tore the anterior cruciate ligament in his knee Wednesday night during a non-contact drill.
Rosenbach said at a news conference that he made the decision after consulting with orthopedic specialists Russell Chick, the team physician, and Steve Lombardo of the Kerlan-Jobe clinic in Inglewood, Calif.
Last season, Rosenbach threw for 3,098 yards and rushed for 470, second among NFL quarterbacks. His preseason was highlighted by his 13-for-16 passing performance in a 46-0 victory over the New England Patriots.
Tom Tupa, who started two games in 1989 but did not take a snap last season, filled in Friday night against the Denver Broncos. The fourth-year pro from Ohio State completed seven of 13 passes for 119 yards, as the Cardinals rolled to a 34-10 victory that gave them a 4-0 preseason record.
* COLTS: Running back Albert Bentley suffered a separated shoulder during a 23-21 loss to the Eagles on Friday night and could miss four to six weeks.
Bentley was hurt when he was drilled by safety Andre Waters after catching a 14-yard pass late in the first half.
* CHARGERS: Coach Dan Henning switched starting quarterbacks Friday night, immediately after the team lost its third straight preseason game.
John Friesz, who completed 17 of 19 passes for 210 yards and one touchdown in just three drives in a 17-7 loss to the Raiders, is the new starter. Friesz completed his first 11 passes, including four for 66 yards on the Chargers' only scoring drive.
Until Friday night, Billy Joe Tolliver had been the starter. He had completed only 50.9 percent of his passes, but neither Friesz nor third-string quarterback Bob Gagliano had dislodged him.
* BROWNS: Pro Bowl defensive tackle Michael Dean Perry said there is a possibility he will sit out the season.
In his first public comments during his long holdout, Perry said in an interview with WEWS-TV on Thursday night: "I could sit out all season. Hopefully, it won't come to that. We could get this thing settled in a matter of days, and I could be ready for the first game against Dallas [Sept. 1]. If not, I could possibly be out for a little bit of the season. Who knows?"
In Perry's absence, rookie Frank Conover has been starting at right defensive tackle. Conover, the team's eighth-round draft pick from Syracuse, was 19th on the team with three tackles in three exhibition games. He also had a forced fumble and a fumble recovery.
* PACKERS: Place-kicker Chris Jacke, frustrated by negotiations a two-year contract, is prepared to end his holdout, published reports say.
Both the Milwaukee Sentinel and Milwaukee Journal said Jacke is close to signing.
Agent Steve Weinberg said the kicker and team have agreed on $300,000 for 1991 compensation. The snag has been in the second year; the Packers increased their 1992 offer to $340,000 from $325,000, but Jacke had been seeking about $375,000.
* EAGLES: Jim McMahon relieved Randall Cunningham two minutes into the second quarter of a 23-21 victory over Indianapolis on Friday night, and in 32 minutes completed 12 of 21 passes for 158 yards.
"I'm real happy to see him get into the swing of things and get his rhythm going," Eagles coach Rich Kotite said. "We have two quarterbacks who are outstanding together. He was very alert and very sharp. I wanted him to get the work."
McMahon suffered a bruised leg and sprained ankle in the
second preseason game and hadn't played since.
