Free agent quarterback Elvis Grbac, Steve Young's backup with San Francisco, has agreed in principle to a contract with the Kansas City Chiefs.
Grbac has not signed a contract, Chiefs spokesman Pete Moris said Friday. Moris said it was unknown when the contract would be signed.
"It has been a situation that has developed as the day went on," Moris said.
Someone who answered the phone and declined to be identified at the 49ers' office said the team had no immediate comment about the agreement.
Grbac, 26, is a four-year veteran who went to San Francisco as an eighth-round draft choice in 1993. He spent all that time backing up Young.
He would become the third straight starting quarterback the Chiefs had taken from the 49ers, following Joe Montana and Steve Bono.
BONIOL TO EAGLES:Placekicker Chris Boniol, the offensive standout for the Dallas Cowboys last season, joined punter John Jett as an off-season, free agent defection Friday, taking a $2.45 million offer from the Philadelphia Eagles.
The Cowboys, who have salary cap problems, failed to match the four-year offer which gives Boniol $800,000 in 1997, including a $150,000 bonus. Boniol receives salaries of $500,000 in 1998 and 1999, and $650,000 in 2000.
Dallas had made a $361,000 offer so it would have the right to match any offers.
"Chris did a great job for us," Cowboys owner Jerry Jones said in a statement Friday announcing the team's decision. "He was a big part of our success over the past three seasons, and we all wish him the best."
Dallas coach Barry Switzer said he hated to lose Boniol because "he's a great kid and a great pressure kicker, but that's more than we can afford to pay."
Boniol made 32 of 36 field goals last season including his last 27 in a row. He made an NFL record-tying seven field goals in a win over the Super Bowl champion Green Bay Packers.
Boniol also made the game-winning 29-yard field goal in overtime against San Francisco. Two years ago he made a dramatic 35-yard field goal as time expired, leading Dallas over the New York Giants.
Boniol made 81 of 93 field goals in his three-year career with the Cowboys, after joining them as a rookie free agent from Louisiana Tech in 1994.
The Cowboys lost Jett to the Detroit Lions. Jett also was Boniol's holder.
Dallas was about $900,000 under the $41.45 million salary cap and hope to sign fullback Daryl Johnston, who is a free agent.
Boniol said he understood his contract was just business.
"I hoped I could stay in Dallas, but once I got the Philadelphia offer I figured things wouldn't work out," Boniol said. "I had to take the best offer. I'll miss Dallas."
Boniol also might miss Texas Stadium which provides more ideal conditions for a placekicker than windy and cold Veterans Stadium.
