The 49ers have the day off, but there was plenty of significant developments in the early games Sunday.
--The NFC West-leading Seattle Seahawks faced the Houston Texans, who travel to Candlestick next week for a Sunday night game.
Houston led the Seahawks by 14 points in the fourth quarter. Then, the Texans imploded. San Francisco Public Enemy No. 1, Seahawks cornerback Richard Sherman, had a 58-yard interception return of a Matt Schaub pick with 2:40 remaining in regulation to send it to overtime.
And the Seahawks (4-0) won in overtime to maintain a two-game lead over the 49ers and Arizona Cardinals in the division.
Texans linebacker Brian Cushing sustained a concussion. He must pass the NFL's protocol on concussions to return to action to face the 49ers.
--The Cardinals rallied to beat the Tampa Bay Buccaneers to even their record. Ex-49ers safety Dashon Goldson was called for a helmet-to-helmet hit late in the game to set up the Cardinals’ winning points.
Goldson, a multiple illegal hit offender, escaped a suspension two weeks ago upon appeal. Now, it seems realistic to assume the suspension will stick this time.
Meanwhile, rookie Eric Reid has played very well. At this point, there’s nobody with the 49ers who is not pleased that Reid is the starter and Goldson – and his exorbitant salary – is with Tampa Bay.
--The Kansas City Chiefs are 4-0 with Alex Smith at quarterback. If the Chiefs finish with a 4-8 record or better, the 49ers will receive a second-round draft pick to complete the deal that sent Smith to Kansas City.
Smith threw an uncharacteristic two interceptions in the Chiefs’ 31-7 victory over the winless New York Giants. However, Smith also completed 24 of 41 passes for 288 yards and three touchdowns.
--The 49ers made a miscalculation with their decision to waive rookie cornerback Marcus Cooper. They wanted to bring him back to the practice squad. Instead, the Chiefs claimed Cooper off waivers.
Now, Cooper (6 foot 2) is the Chiefs’ No. 3 cornerback. On Sunday, he broke up two passes – a deep route intended for Rueben Randle and a short pass for Hakeem Nicks.
The 49ers have plenty of questions about the future of their cornerback position, and Cooper seemingly had a long-term future with the organization.
Chris Culliver, who is out for the season with a torn ACL, is the only experienced 49ers player who seems certain to return. It appears unlikely the 49ers will retain Carlos Rogers at his scheduled $6.6 million price tag. Tarell Brown, Nnamdi Asomugha and Tramaine Brock are all scheduled for free agency.
