O'Brien received a qualifying offer Monday.

EDGE Analysis

O'Brien logged three games for the Capitals in 2017-18 and logged five penalty minutes. The rugged 24-year-old is likely ticketed for another season in the minors for 2018-19.

The Capitals reassigned O'Brien to AHL Hershey on Saturday.

EDGE Analysis

O'Brien drew into three games during his stay with the big club, but he only averaged 6:55 of ice time during those contests, so his demotion doesn't come as much of a surprise. The 23-year-old forward will remain with AHL Hershey for the majority of the 2017-18 campaign.

O'Brien was promoted from AHL Hershey on Thursday.

EDGE Analysis

O'Brien is off to a slow start for the Bears this season, as he has just two points in nine minor-league games. The center will now get a chance to make his 2017-18 debut, although coach Barry Trotz may just utilize him as an emergency depth option against the Islanders on Thursday. In a corresponding move, Anthony Peluso was sent down to the AHL.

Washington waived O'Brien (lower body) on Tuesday.

EDGE Analysis

O'Brien was dealing with a minor lower-body ailment last week, but his placement on waivers indicates he's fully recovered from that injury. The 23-year-old forward was decent in the minors last season, notching 30 points (10 goals, 20 assists) in 64 games with AHL Hershey, but he likely won't ever hold a regular spot in an NHL club's lineup.

O'Brien did not practice Tuesday and is considered day-to-day with a lower-body injury, Isabelle Khurshudyan of the Washington Post reports.

EDGE Analysis

O'Brien likely sustained the injury during Washington's loss to New Jersey on Monday night. With the young pivot already facing an uphill battle to make the Opening Night roster, this is certainly not the setback he needed, so he'll look to get healthy as quickly as possible in order to get back on the ice and continue his quest.

O'Brien finalized a one-year, two-way contract with Washington on Friday.

EDGE Analysis

O'Brien has suited up in 14 NHL contests since going undrafted out of the QMJHL. In those outings, the center recorded one goal, one helper and 23 PIM. Considering the 22-year-old racked up 30 points in 64 appearances for AHL Hershey last season, it makes sense that the Caps were willing to sign him for another year. Given the number of holes in Washington's lineup, a strong camp from O'Brien could land him a spot on the 23-man roster.

O'Brien was re-assigned to the AHL's Hershey Bears Tuesday.

EDGE Analysis

O'Brien saw brief action on Washington's fourth line in Monday's 4-1 win over the Canadiens but recorded just one hit in the contest. The 22-year-old forward will look to build on the 21 points he has with the Bears this season as he hopes for another crack at the NHL ranks in the future.

O'Brien will be in the lineup Monday against the Canadiens

EDGE Analysis

Called up due to the injury to T.J. Oshie (upper body), O'Brien should make his debut on the fourth line with Jay Beagle and Tom Wilson. The 22-year-old forward has five goals and 21 points in 28 games with AHL Hershey this season, but his fantasy value remains limited unless he can carve out a meaningful role during Oshie's absence.

O'Brien was promoted from the minors Friday.

EDGE Analysis

With the Capitals relatively healthy all season long, they have not needed to carry their full 23-man compliment of players, instead opting for just 22. That strategy has changed with the call-up of O'Brien, which could mean the team is starting to pick up some of the bumps and bruises that come with an 82-game season. The 22-year-old has tallied five goals and 13 helpers in 28 minor-league contests and could be worth keeping an eye on in dynasty formats.

O'Brien was released by the Capitals on Monday.

EDGE Analysis

O'Brien played just 13 games with the Capitals last season, and his 45 AHL games didn't produce much either. The 21-year-old center collected just eight points (four goals, four assists) with AHL Hershey, and has now become a free agent. Given his age, it's quite possible another team will sign O'Brien as organizational depth.
