The Oakland Raiders could be looking for more help along their already-stellar offensive line in this year's draft.

According to Aaron Wilson of the Houston Chronicle, the Raiders are one of five teams that is scheduled to host offensive tackle Julie'n Davenport out of Bucknell for a pre-draft visit. Davenport has already visited four other teams.

Davenport measured at 6-foot-7 and 318 pounds at the NFL Scouting Combine in Indianapolis earlier this month. He is a monster lineman who CBS Sports ranks as the 13th best tackle in this year's draft class and the 147th best prospect overall. He is projected to be selected in either the fourth or the fifth round.

The Raiders fielded one of the NFL's finest offensive lines last season. They allowed a league-low 18 sacks and finished the season with the sixth ranked rushing attack (120.1 yards per game). They had three different offensive linemen — left tackle Donald Penn, left guard Kelechi Osemele and center Rodney Hudson — get voted into the Pro Bowl.

Also strong at the right guard position with Gabe Jackson holding it down on the opposite side of Hudson, the Raiders have an opening at right tackle. Menelik Watson (signed with Broncos) left in free agency, and Austin Howard isn't a lock to win the starting job again in 2017. Other options to replace him are Vadal Alexander, Denver Kirkland and recent free-agency acquisition Marshall Newhouse.

The Raiders could draft Davenport in one of the middle to late rounds of the draft and allow him to join the wide-open position battle. With 36.5-inch arms, he also has the prototypical size for an NFL left tackle. Perhaps he could be groomed to one day take over as Donald Penn's long-term replacement on the blind side.

Davenport started 44 games at left tackle during his collegiate career and could be a quality addition for the Raiders.
