At this point, there is a good chance that Jackson will miss Sunday's game against the Tennessee Titans in Nashville.
Robinson, who also sustained a concussion in last Sunday's game, was fined $50,000 by the NFL for hitting Jackson in the helmet early in the second quarter of Atlanta's 31-17 loss to Philadelphia. Robinson said Tuesday that he will appeal the fine because he believes the hit didn't violate league rules.
Jackson had staked the Eagles to a 14-0 lead, rushing twice for 44 yards and one touchdown (on a 31-yard run) and catching a 34-yard scoring pass from Kevin Kolb.
The third-year standout from the University of California has 19 receptions for 395 yards and three touchdowns this season after catching 62 passes in each of his first two seasons, gaining 912 yards and scoring twice as a rookie and amassing 1,156 yards and nine touchdowns last year.
