If you’ve been following our coverage of the Houston Astros’ 2026 injury spiral, brace yourself for another round of bad news.
Three more players have been added to an already staggering list of wounded players.
Allen is now the 15th player to go on the IL for Houston, a stunning number for a team that has played just 23 games.
The latest wave hits the outfield and infield simultaneously, stretching the roster to its breaking point.
Taylor Trammell — Left Groin Strain
Trammell was called up from Triple-A Sugar Land precisely to help cover an outfield already depleted by Jake Meyers’ oblique injury. He didn’t last long.
Trammell exited Monday’s game against the Guardians in the fourth inning after feeling his groin tighten while sliding into third base. To his credit, he showed sound injury management instincts in the moment. “Be smart,” he told himself. “It’s still April.”
From a sports medicine perspective, an acute groin strain sustained during a deceleration slide is a classic adductor muscle injury, typically the adductor longus.
Management in the acute phase centers on relative rest, ice, and soft tissue offloading. As pain subsides, progressive hip strengthening, adductor flexibility work, and sport-specific running mechanics become the focus before return to play.
Trammell himself sounded cautiously optimistic, noting he had no major red flags and was hopeful for a relatively short recovery.
A Grade 1 groin strain typically resolves in 10 to 14 days, though Grade 2 involvement could push the timeline to 3 to 4 weeks, particularly given the rotational and explosive demands of outfield play.
Joey Loperfido — Left Quad Strain
Loperfido was removed with a quad injury in the sixth inning of Friday’s loss to the Cardinals and subsequently underwent an MRI.
The Astros placed him on the 10-day IL with a left quad strain on Sunday.
Loperfido had appeared in nearly every game this season and was carrying a solid .259/.333/.345 slash line before going down.
A quadriceps strain in a baseball player most commonly involves the rectus femoris, the muscle most vulnerable to eccentric loading during explosive sprinting movements like rounding the bases or tracking fly balls.
Acute treatment follows the standard PRICE protocol, transitioning to progressive resistance training and neuromuscular retraining as healing progresses.
Quad strains respond well to conservative management, and a 10-day IL stint is reasonable for a mild to moderate strain.
If imaging confirms Grade 2 involvement, a 3 to 5 week absence is more realistic before Loperfido is cleared for full baseball activity.
Nick Allen — Back Spasms
Nick Allen was knocked out of Friday’s Cardinals game, with Isaac Paredes replacing him due to back spasms.
The Astros formally placed Allen on the 10-day IL on Monday.
The 27-year-old was batting .250 with five runs scored over 14 games this season.
Back spasms in an infielder are commonly traced to lumbar paraspinal muscle overactivation, often exacerbated by the repeated lateral loading and quick-twitch rotational demands of fielding and throwing.
In many cases, acute back spasms resolve within 7 to 14 days with a combination of anti-inflammatory medication, manual therapy, dry needling, and targeted core stabilization work.
The key return-to-play consideration for an infielder like Allen is restoring pain-free lumbar mobility and rotational stability under load before progressive fielding activities resume.
The 10-day IL designation is appropriately conservative here, though recurrence risk remains elevated if underlying movement compensations are not addressed.
The Bigger Picture
The Astros currently have 13 players on the injured list, and all these injuries have forced some Triple-A players and midseason depth options into critical roles far earlier than intended.
What began as a pitching crisis has now consumed the outfield and infield depth as well.
From an organizational sports medicine standpoint, the clustering of lower extremity and lumbar injuries across multiple players warrants a hard look at workload accumulation, travel fatigue, and early-season conditioning protocols.
The Astros need answers quickly.
