The luck factor in fantasy football, especially during the postseason, is so frustrating!

The 49ers formally dropped their tampering case against the Jets regarding rookie WR Michael Crabtree, according to a source with knowledge of the situation.

The jawing between Adewale Ogunleye and Vernon Davis before the game was no joke. I was right on the sidelines and at one point I thought they were gonna throw down. Cooler heads prevailed.

The 49ers don’t plan to dress veteran WR Isaac Bruce for Thursday night’s home game against the Bears, choosing to rest him instead, league sources told NFL Network’s Jason La Canfora.

Michael Crabtree started against the Texans, as the 49ers opened in a three-receiver set. The 49ers attempted to go to Crabtree on their first play from scrimmage, but Texans DE Mario Williams sacked QB Shaun Hill.

Ever the fan of expression through his favorite social networking site, Bengals WR Chad Ochocino was at it again on Twitter, instigating an exchange of trash-talking tweets with Bears QB Jay Cutler and DE Alex Brown ahead of Sunday’s matchup in Chicago — and the game is still five days away.

Deion Sanders will be interviewed by league insider Jason LaCanfora on NFL Network’s NFL GameDay Morning, which starts at 9 a.m. ET Sunday, and will discuss his relationship with rookie WR Michael Crabtree, who signed with the 49ers this week.

I’m trying my best to withhold judgment on the wide receiver acquisitions on both coasts yesterday — Braylon Edwards getting traded to the Jets and Michael Crabtree signing with the 49ers — but it’s difficult.

Michael Crabtree, the No. 10 overall draft pick, received $17 million guaranteed from the 49ers in a six-year deal that has a minimum base value of $32 million and a maximum value of $40 million.

Michael Crabtree won’t play in the 49ers’ game against the Falcons on Sunday. But the 10th overall pick in the 2009 NFL Draft finally signed and was officially introduced by 49ers coach Mike Singletary today.

The San Francisco 49ers have reached agreement with holdout first-round draft pick Michael Crabtree, according to multiple sources. NFL Network’s Jason La Canfora reports that Crabtree’s contract is being reviewed by the NFL but he has signed, according to a source.
