Horn questionable vs. Carolina Sunday

It appears that the chances of Atlanta Falcons wide receiver Joe Horn playing this Sunday are slim due to an ailing hamstring; Horn was listed as questionable for this Sunday’s matchup against the Carolina Panthers.  What’s strange about this development is the fact that he experienced no physical problems at practice for the entire week.  Horn really hasn’t made much of an impact this season, catching 18 balls for 165 yards.  Expect reserve Laurent Robinson to replace Horn in the meantime.
