The NFL did not fine McDonald for his tackle of 49ers tight end Vernon Davis by the private area. In a tweet Monday (since deleted), Davis asked the NFL to not allow defenders to tackle by that area.
The only fine in the physical game was given to 49ers guard Adam Snyder, who will pay $7,875 for a striking an opponent late.
In other 49ers notes:
49ers left tackle Joe Staley, who suffered a knee injury last Sunday, told San Francisco radio station 95.7 The Game on Friday morning that he expects to play against Seattle. That became evident Thursday when he practiced. More information should be available after Friday's practice, but barring a setback Staley looks good to go.
Joe Montana told The Game that he may not attend the final game at Candlestick Park because of a scheduling conflict. The team is going to honor "The Catch," the famous pass from Montana to Dwight Clark that beat Dallas and sent the 49ers to their first Super Bowl in 1982.
Meanwhile, if you want to attend that final game at Candlestick, it is going to cost you.
