April 1 is the informal deadline for Isaac Bruce to make a decision about retirement. The 49ers want to know if their leading receiver will walk away after a 15th NFL season.
Until then, they're willing to wait. Bruce, 36, was not at the 49ers' voluntary minicamp, which opened Friday.
"When you've done the things that he's done, you just kind of sit back and weigh your options and try to figure it out," coach Mike Singletary said. "He's still working out "... but he's just making sure he's fully committed when he comes back."

The Dolphins added to their defensive line depth by trading a seventh-round draft pick to Jacksonville for defensive tackle Tony McDaniel, who started three games for the Jaguars in 2008.
McDaniel, a 24-year-old with two years left on his contract, is 6-7, 310 pounds. That is not a squat, nose-guard kind of build, so don't expect McDaniel to be part of the answer to who will succeed Jason Ferguson as the Dolphins 3-4 nose guard. But,it's a build for a 3-4 defensive end or a defensive tackle when the Dolphins switch to a 4-3.

EDEN PRAIRIE, Minn. — The Minnesota Vikings have signed free agent wide receiver and kick returner Glenn Holt and unrestricted free agent cornerback Karl Paymah.
Holt is a four-year veteran who led the Cincinnati Bengals in kickoff return yards in each of his three seasons with the team, averaging 24.3 yards per return.
In 2008, Holt had 46 returns for 1,110 yards, with five returns greater than 40 yards. He started at wide receiver for the Bengals the final five games of the season.

While Miami Beach police await a toxicology report on Donte Stallworth, the Browns receiver has returned to Cleveland and has been working out in the team's voluntary off-season program, his attorney, Chris Lyons, told The Plain Dealer.
Police said it's unlikely they'll receive the report over the weekend, meaning charges might be filed against Stallworth on Monday or Tuesday at the earliest.
