i would suggest that this is not a good sign for lamar's likelihood to practice or play this week
given that it's a bone bruise and not a low ankle sprain i do wonder if we see lamar at all the rest of the season - if it's a big one or a nasty one they can take months - it's an injury with massive variance in recovery time but normally range of recovery times are between 4 and 8 weeks
this will be week 3 for lamar (it's not inconceivable he could return but im not particularly hopeful given that he hasnt practiced yet and it seems like he wont today either based on this evidence)
