NEW YORK -- Tim Tebow has work to do if he's going to win over New York sports fans.

The new backup quarterback for the Jets was booed at Yankee Stadium on Sunday night when he was shown on the giant video board -- even though he was wearing a Yankees cap.

Sitting in the third row next to the Los Angeles Angels dugout, Tebow cracked a smile and acknowledged the camera. There was a smattering of cheers, but most of the initial reactions were boos.

Tebow was acquired by the New York Jets from Denver in a much-hyped trade last month. He is expected to back up starter Mark Sanchez, even though Tebow rallied the Broncos to the NFL playoffs last season and became a polarizing sensation in the process.

Sitting next to Tebow was Miami Heat star Dwyane Wade, also booed when he was shown on the scoreboard earlier in the game. But those boos quickly turned to cheers when Wade held up his Yankees cap.

Knicks rookie guard Iman Shumpert was also in attendance. Shumpert was the first of the three players shown on the big screen, receiving a nice round of applause.

Tebow and Wade were gone by the seventh.

The Yankees did not meet with Tebow.

"I didn't get a chance to see him," Yankees manager Joe Girardi said after his team's 11-5 victory. "I would have loved to get a chance to see him and talk to him. I'm sure he'll be back at some point. Obviously he's going to be around a lot more now. But I'd love to visit with him at some point."

He added: "He's one big quarterback. I see him in the stands, he doesn't look like a quarterback."

Yankees right fielder Nick Swisher has met Tebow before and, after being asked several questions about the quarterback, joked that he thought he'd be talking more about baseball than Tebow.

"There are a lot of fancy people that come to these games man," Swisher said when asked about noticing the reaction for Tebow. "Welcome to New York, Tim."

All Major League Baseball players and coaches wore number 42 on Sunday in honor of Jackie Robinson breaking baseball's color barrier on April 15, 1947.

"It was an honor to be at Yankee Stadium tonight on Jackie Robinson Day...65 yrs ago he broke down barriers...," Wade tweeted Sunday night.
