Cardinals manager Oliver Marmol said Monday that Herrera will miss at least four weeks after being diagnosed with a bone bruise in his left knee, Daniel Guerrero of the St. Louis Post-Dispatch reports.

EDGE Analysis

Testing on Herrera's knee came back negative for structural damage, but the bone bruise is going to cost the young catcher a month of action, at minimum. Pedro Pages will take on the primary catcher duties for the Cardinals while Herrera is out, and Yohel Pozo has been called up from Triple-A Memphis to serve as Pages' backup.

The Cardinals placed Herrera (knee) on the 10-day injured list Monday.

EDGE Analysis

Herrera tweaked his left knee while running the bases in the first game of Sunday's doubleheader versus the Red Sox. He was diagnosed with inflammation after tests on his knee came back negative, but Herrera has since headed back to St. Louis to be evaluated further before the Cardinals determine how long he might be out. While Herrera is sidelined, Pedro Pages will serve as the Cardinals' primary catcher.

Herrera (knee) is expected to be placed on the 10-day injured list, John Denton of MLB.com reports.

EDGE Analysis

Herrera underwent additional imaging after exiting Game 1 of Sunday's doubleheader early with left knee inflammation. The tests came back clean and "it could've been a lot worse," according to manager Oli Marmol, who continued by saying, "he'll go on the IL, but it could have been a bad situation." Pedro Pages drew the start in Sunday's nightcap behind the plate and he'll likely handle the lion's share of starts at catcher in Herrera's absence.

Herrera was diagnosed with left knee inflammation after exiting in the third inning of the first game of Sunday's doubleheader versus the Red Sox, Gabrielle Starr of the Boston Herald reports.

EDGE Analysis

Herrera went 0-for-1 with a walk before leaving the contest after he appeared to injure his knee while running the bases. Pedro Pages came off the bench to replace Herrera in the bottom of the third inning and will finish out the game behind the plate while also drawing the start at catcher in the nightcap. The Cardinals seem to be viewing Herrera as day-to-day, though he could be at risk of landing on the IL if he's not able to return to the lineup within the next few games.

Herrera was removed from Game 1 of Sunday's doubleheader against the Red Sox due to an apparent leg injury, Katie Woo of The Athletic reports.

EDGE Analysis

Herrera worked a walk during the bottom of the third inning but suffered an injury while running the bases and required assistance to leave the field. The 24-year-old was already likely to sit for Game 2 after starting the matinee, but his availability beyond Sunday is now in question. Pedro Pages stepped in behind the plate and would operate as St. Louis' primary catcher should Herrera be forced to miss time.

Herrera isn't in the lineup for Saturday's game versus Boston, John Denton of MLB.com reports.

EDGE Analysis

After slugging four home runs and tallying nine RBI over his last two games, Herrera will take a seat Saturday to give Pedro Pages a chance to start behind the plate.

Herrera went 3-for-4 with a walk, three home runs and six RBI in Wednesday's 12-5 win over the Angels.

EDGE Analysis

The 24-year-old took Yusei Kikuchi deep in the fourth and sixth innings before capping his huge performance with an eighth-inning blast off Brock Burke. In the process, Herrera became the first catcher in Cardinals history with a three-homer game. The long balls were also the first of the season for Herrera, and through five appearances so far in 2025 he's batting .467 (7-for-15) with two doubles, five runs and eight RBI.

Herrera will start throwing from his knees in hopes that it will help him better control the running game, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

Baserunners are 5-for-5 on stolen base attempts against Herrera this season and 60-for-64 since the beginning of last year. The throwing problems have led to Herrera sometimes being removed from games he starts in the later innings when the Cardinals need to prioritize defense. Herrera clubbed three home runs in Wednesday's game versus the Angels, and the Cardinals want to keep his bat in the lineup as often as possible. Improving his throwing will help ensure that.

Herrera is not in the lineup for Tuesday's contest against the Angels.

EDGE Analysis

Herrera -- who sports a 1.055 OPS in the early going -- has now drawn three starts to Pedro Pages' two in the first five games. Pages will do the catching for Matthew Liberatore on Tuesday.

Herrera is out of the lineup for Sunday's game against the Twins, John Denton of MLB.com reports.

EDGE Analysis

Herrera started the first two games of the season and went 4-for-7 with a walk, two doubles, two RBI and a run, and he'll receive a well-deserved rest Sunday. Pedro Pages is stepping in behind the plate to catch for righty Andre Pallante.
