Spencer had arthroscopic knee surgery yesterday and he will be out 2-4 weeks.
Spencer was hurt in the preseason opener at San Diego with what initially was diagnosed as a bone bruise. He missed last week's game at Denver because of swelling in the knee. Spencer said he wanted to practice but the swelling in his knee would subside one day then come back.
The Cowboys took another look at the knee, and they decided surgery was necessary.
I still expect 2008 to be a breakout year for Spencer. Hopefully, he'll miss closer to 2 weeks instead of 4 weeks.
