This could factor into the field-position battle tonight. Supulveda, who beat out Kapinos in training camp, was netting 40.6 yards on punts this season. Kapinos had a 32.3-yard net average in four games for Pittsburgh last season.
In last season's playoff game against Baltimore, it was Kapinos who out-kicked his coverage and allowed Lardarius Webb to score on a 56-yard return. But that touchdown was negated by a holding penalty on the Ravens' Marcus Smith.
Webb ranks 24th in the league with an 8-yard punt return average this season.
