No structural damage was seen with Ryu's shoulder and he was prescribed two-to-three weeks of rest before he resumes throwing, CBS Sports' Jon Heyman reports.

It's obviously still concerning, as he will certainly miss his first turn through the rotation, and may need a rehab start or two before joining the rotation following his period of rest. He should continue to be discounted in drafts, but he should not be completely ignored, as there is a chance he could slot back into the mix in late April. As of now, Juan Nicasio and Joe Wieland might be the Dodgers' best in-house options to replace Ryu in the rotation to start the season.

Ryu is not expected to be ready for Opening Day after he felt discomfort in his shoulder Sunday and was sent back to Los Angeles, Bill Shaikin of the Los Angeles Times reports.

Ryu's status was already in limbo for Opening Day and on Sunday manager Don Mattingly admitted that Ryu will miss the beginning of the season. The 27-year-old will head back to the Dodgers' facilities to get treatment over the next few weeks but his availaibility moving forward is in serious question until the team gives him a firm timetable for a return to the mound. As a result, it may be wise to consider other options in place of Ryu.

Ryu has been shut down with left shoulder inflammation and received an injection, Bill Shaikin of the Los Angeles Times reports.

This is not good. Not only does it add to Ryu's recent back issues and make Opening Day readiness a heavy improbability, but this also comes after a 2014 season limited by shoulder issues. If Ryu is healthy, he's one of the top No. 3 pitchers in baseball, but shoulder issues can linger for a long time and limit him throughout the season. Unless we get some really good news in the next three days, he's an extraordinarily risky draft pick.

Ryu tossed a pair of scoreless innings against the Padres on Thursday in what was his Cactus League debut.

Ryu (back) will throw a live bullpen session Saturday and will rejoin the rotation next Thursday, Bill Plunkett of the Orange County Register reports.

Ryu threw a bullpen session Monday, and will pitch against live batting for the first time Sunday, but appears to be progressing as needed to be ready for the beginning of the regular season. While he will be a bit behind some of the other starters, he will still have a good chunk of spring training to stretch out his arm.

Ryu (back) threw a bullpen session Monday and will need another session and a simulated game before the club considers having him appear in a game, Eric Stephen of True Blue LA reports.

At this point, Ryu should be available for the start of the season barring a setback.

Ryu (back) is tentatively scheduled to throw a bullpen session Monday, the Los Angeles Times reports.

The left-hander emerged from Tuesday's bullpen session with some mid-back tightness, but Ryu said he thought the issue was not serious and a subsequent MRI was returned negative. He was cleared to resume throwing on flat ground Friday and it looks like the issue will indeed end up delaying Ryu just a few days, as he suggested would be the case.

An MRI on Ryu's ailing back showed no structural damage, SB Nation reports.

The Dodgers held Ryu out of workouts again Thursday after the lefty experienced some mid-back tightness following Tuesday's bullpen session. However, Ryu has expressed confidence that the issue is not serious, and the results of the MRI suggest that is indeed the case. It's still uncertain when Ryu may return to elevated ground, but he thinks the injury will push his schedule back "a few days at most."

Ryu is confident that his back issue is not serious, Dylan Hernandez of the Los Angeles Times reports.

Ryu is currently fighting through a bout of mid-back tightness, which surfaced following a bullpen session Tuesday. The lefty continues to downplay the severity of the ailment, saying that he expects to return to mound work within a matter of days, but it still seems like something that could affect Ryu's availability for the start of Cactus League action.

Ryu did not participate in in the Dodgers' workout Wednesday due to "mid-back tightness" following a bullpen session Tuesday, Bill Plunkett of the Orange County Register reports.

Ryu is aiming for 200-plus innings in 2015, and the mid-back tightness shouldn't prevent him from doing that assuming it doesn't turn into anything more serious. Still, it's worth monitoring in case something more does come of the situation. On the plus side, Ryu hasn't experienced any shoulder issues, which caused him problems late in the 2014 campaign.
