After sitting out a 2-1 victory Thursday against the Buffalo Sabres with a lower-body injury, Jackman will come back into the lineup Saturday for the Blues (52-17-7) against the Colorado Avalanche (49-21-6).
Jackman was among those to skate Friday in an optional practice and deemed himself fit.
"Other guys got in the lineup and we're rested and ready to go [Saturday]," Jackman said. "Two days off. It felt good so we're ready to go [Saturday]. … Every game's a grind from here on out. I got two days' rest, which is only going to be beneficial down the stretch."
