"We're going to be better when we get those players," the Bucs' coach said Monday.
Tampa Bay has relied on wide receiver Mike Evans the past three games after Jackson went out with a knee injury in a Week 7 loss to the Washington Redskins. Seferian-Jenkins hasn't played since suffering a shoulder injury in a Week 2 win over the New Orleans Saints.
Evans has 662 yards on 40 catches this season, and it was clear Sunday in a win over the Dallas Cowboys that the Bucs didn't have many other legitimate pass-catching options. Beyond Evans' game-high 126 yards receiving, running back Doug Martin had 40. Tight end Brandon Myers totaled 35, and wide receiver Adam Humphries 25.
"This was sweet," Evans said of Sunday's victory. "We needed this one. ... We got Austin out and V-Jax out. It's been tough, but we just kept fighting and we got the W."
Jackson is second on the team in receiving with 319 yards, and Seferian-Jenkins was leading the Bucs with 139 when injured.
"When a guy is out, it's a process," Smith said. "It takes a little bit of time to heal."
