Smelter (concussion) returned to the Jaguars' practice Saturday, John Oehser of the Jaguars' official site reports.

EDGE Analysis

Smelter sat out practice this week as well as Thursday's preseason opener as he was unable to clear the concussion protocol. The 26-year-old can ill afford to miss any additional time if he has any chance of cracking Jacksonville's 53-man roster.

Smelter sat out Thursday's preseason opener against the Saints due to a concussion, Mike Kaye of FirstCoastNews.com reports.

EDGE Analysis

Smelter first missed practice Monday and was unable to practice the rest of the week. The 26-year-old will have to clear the league-mandated concussion protocol before returning to practice in full.

Smelter (undisclosed) is not expected to play Thursday against the Saints, John Oehser of the Jaguars' official site reports.

EDGE Analysis

Smelter has missed practice time due to an undisclosed issue and it appears he will miss an opportunity to make an impression on the coaching staff in the preseason opener. Look for him to take aim at returning to live game action for Week 2 of the preseason as he battles for a spot on the 53-man roster.

Smelter was held out of practice Monday with an undisclosed injury, Mike Kaye of FirstCoastNews.com reports.

EDGE Analysis

A fourth-round pick by the 49ers in 2015, Smelter resides at the bottom of a fairly deep Jaguars' wide receiver depth chart. The 26-year-old, who has appeared in only two NFL games, faces an uphill battle to make the 53-man roster and cannot afford to spend much time sidelined.

Smelter signed a contract with the Jaguars on Friday, Hays Carlyon of 1010 AM WJXL reports.

EDGE Analysis

A fourth-round pick by the 49ers in 2015, Smelter has bounced around a bit the past few years. He'll be looking to secure a depth and special teams role while in Jacksonville for the 2018 season.

Smelter was waived by the Colts on Friday.

EDGE Analysis

Smelter signed a reserve/future contract with the Colts in January, but was let go in favor of fellow wide receiver Kasen Williams. The 26-year-old spent the 2017 season on the 49ers' practice squad and will hope to latch on elsewhere for 2018.

Smelter signed a reserve/future contract with the Colts on Wednesday, Mike Chappell of Fox 59 News reports.

EDGE Analysis

Smelter spent the 2017 season on the 49ers' practice squad after being waived by the team at roster cutdowns in September.

Smelter agreed to join the 49ers' practice squad Monday.

EDGE Analysis

Smelter had a strong start to training camp, but was unable to crack the final roster. He will now look to impress on the team's practice squad, where he also spent the majority of last season.

Smelter was waived by the 49ers on Saturday, Nick Wagoner of ESPN reports.

EDGE Analysis

Despite a strong start to training camp, Smelter was unable to distinguish himself throughout the preseason. If he clears waivers, he could be a candidate for the practice squad.

Smelter has been "coming on strong" a week into training camp, Matt Maiocco of NBC Sports Bay Area reports.

EDGE Analysis

Lower-body injuries limited the 2015 fourth-round pick in his first two seasons with the 49ers, but he appears to be healthy in camp for the first time in his career. Smelter remains fairly low on the receiver depth chart, but he could work his way up if he continues to show improvement this preseason. The 25-year-old is one of the few big-bodied wideouts (6-foot-2, 227 pounds) on the roster, which could work in his favor should one of San Francisco's starters go down to injury.
